Very Collectible Pair of Vintage Cheese Graters C.1930

Pair of Cheese Graters
Circa 1930
(perhaps earlier)
Larger one measures approximately 15H x 8W"
The second one measures approximately 9H x 5W"
As you can see by the pictures they are all in
great condition
One has a wooden knob while the other one
has a glass knob
I believe the wooden knob is the original to the piece
I believe the glass knob was added later
Happy Bidding!!
